Since it's a right triangle, use the Pythagorean theorem,
\n" ); document.write( " $\"x%5E2%2B%28x%2B1%29%5E2=%28x%2B2%29%5E2\"$
\n" ); document.write( " $\"x%5E2%2Bx%5E2%2B2x%2B1=x%5E2%2B4x%2B4\"$
\n" ); document.write( " $\"x%5E2-2x-3=0\"$
\n" ); document.write( " $\"%28x-3%29%28x%2B1%29=0\"$
\n" ); document.write( "Two solution however since it was stated that x>0 only the positive solution works here.
\n" ); document.write( " $\"x-3=0\"$
\n" ); document.write( " $\"x=3\"$
\n" ); document.write( "So the triangle has sides 3,4,5.
